DOOR PROTECTOR AND CHECK Filed Jan. 23. 1950 INVENTOR BALDWIN W.WENDT ATTORNEYS Patented Nov. 3, 1953 UNITED STATES PATENT OFFICE Baldwin W. Wendt, Milwaukee, Wis.

Application January 23, 1950, Serial No. 140,096

1 Claim. (01. lit-65) This invention appertains to builders hardware, and more particularly to a novel attachment for protecting doors and their hinges against injury through forcible opening swinging movement. I

One of the primary objects of my invention is to provide a door protector and check, which will eifectively cushion the opening swinging movement of doors and which will prevent the opening of doors beyond a certain point to prevent said doors from being torn off their hinges by strong winds, etc.

Another salient object of the invention i to provide a door protector and check, which will effectively function as a brace for the door and which further embodies a guide cylinder and a slide block within the cylinder with means, including a link, for operatively connecting the slide block with the door casing.

A further object of the invention is to provide a cushioning spring in said cylinder for engagement by the slide block, when the door has been opened a predetermined distance for cushioning the further opening movement of said door, the link preventing the door from being opened beyond a certain point and after the cushioning means has been brought into place.

A still further object of the invention is to provide a novel door check and protector of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture and one that can be placed upon the market and applied to a door at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawing, in which drawing,

Figure 1, is a sectional view through a door frame showing my improved device applied to a door and frame, parts of the device being shown in longitudinal section.

Figure 2, is a fragmentary rear elevational view of a door and door frame, with my improved device connected therewith, the link and a portion of the cylinder being partly broken away to illustrate clearly certain details of my improved device. V

Figure 3, is an enlarged fragmentary transverse sectional view taken on the line 33 of Figure 2, looking in the direction of the arrows.

Figure 4, is a view'similar to Figure 3, but taken on the line 4-4 of Figure 2, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate, corresponding parts throughout the several views, the letter 0 generally indicates my improved door protector and check and D a door and Fa door frame with which the device is associated.

The door D and the frame F are of a common type now found in homes and buildings, and neither the door nor the frame will be described in detail, but it is to be noted that the door includes side stiles 5 and 6, and a connecting head 1.

My improved door check and protector C comprises an elongated face plate 8, which extends transversely of a door, preferably adjacent to the upper end thereof; This face plate is of a suincient length to extend over, at least a portion of the side stiles 5 and 6 of the door and the face plate is firmly secured to the inner face of the door by fastening elements 9.

Formed 0n the face plate 8, is a longitudinally extending guide cylinder [0. The cylinder preferably terminates short of the ends of the face plate and one end of the cylinder can be closed by a wall H, and the other end by a removable screw threaded cap l2. The cylinder is provided with a longitudinally extending guide slot l3.

Traveling in the cylinder [0, is a cylindrical slide block I 4, and this block carries an outwardly extending guide ear l5. The ear I5 protrudes through the slot [3 and preferably engages the upper and lower walls of the slot. It is to be noted that for the purpose of assembling or disassembling, the guide ear I5 is detachable from the slide block M. Also disposed within one end of the cylinder, namely, the end of the cylinder adjacent to the hinging point of the door, is an expansion coil spring I6, and the slide block I 4 is adapted to engage the spring and compress the same, as will later appear. The outer end of the guide ear I5, is provided with a pivot openmg.

Firmly secured to the door frame F, adjacent to the hinges of the door is a bracket l1 and this bracket has, pivotally connected thereto as at l8, a link IS. The opposite end of the link 19, is pivotally connected to the ear l5. As shown, the rod I9 is provided with a right angularly extending pivot arm 20, which extends through the opening in the ear l5. A removable pin 2! extends transversely through an opening formed in the lower end of the pivot arm 20 and the pin 2! engages the under surface of the ear i5 thus preventing accidental movement of the pivot arm from said ear.

In use of my improved door protector and check C, upon the opening movement of the door, the slide block [4 will move toward the spring I6 by the link 19 and when the door is approximately half open, the slide block will engage and start to compress the spring [6. Upon further opening movement of the door, the spring is compressed further and further, and functions to cushion the opening movement of the door. As the door reaches its full open position, the link [9 strikes the cylinder and tends to hold the door against further opening movement under the influence of strong winds and the like.

The face plate 8 forms a brace for the upper end of the door to prevent sagging thereof and the slide block 14 and the ear l5 traveling in the guide slot I3 also act to prevent sagging of the door.

From the foregoing description it can be seen that I have provided an exceptionally simple and effective means for protecting doors against forcible opening movement.

The device is of such a simple nature that the same can be readily attached to a door and a door frame by a layman, and without the employment of a skilled mechanic.

Changes in details may be made without de- .4 parting from the spirit or the scope of this invention, but what is claimed as new is:

A door protector and check comprising a face plate adapted to be secured to the inner face of a door transversely of a door and extending from one stile thereof to the other, a longitudinally extending cylinder on said face plate, said cylinder having a longitudinally extending guide slot therein, a slide block movable in said cylinder having a guide ear extending through the slot and engaging the upper and lower walls thereof, a cushion spring in said cylinder for engagement by the slide block upon the opening movement of the door, a bracket adapted to be secured to a door frame adjacent to the hinge point of the door, and a link pivotally connected to the bracket and to the ear of the slide block, said link adapted to engage the cylinder after the slide block has engaged the spring and the door has opened a pre-determined distance.
